Notes:
A single crystal of Sn1.59Nb1.84O6.35 was grown at 1273 K from a mixture of sodium niobate and tin(II) chloride. The structure is of pyrochlore type A2B2O7. The tin is partially oxidized to tin(IV) and competes with niobium for the occupation of site B. The stereoactivity of the Sn2+ lone pair induces displacement of tin towards the O atoms of the tunnel.
